IMPROVEMENT IN .HINGES.

Specification forming part of Letters Patent No. 165,6H9, dated July 13, 1875; application filed December 5, 1874. i

To all whom it mag concern Be it known that I, FRANSESCO L. SAN- DERSON, of Wilmington, in the county of (Jlinton and" State of Ohio, have invented a new and valuable Improvement in Gate- Hinges; and I do hereby declare-that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and-to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a front view of my gate and hinge. Figs. 2, 3, and 4 are views of the hinge.

This invention has relation to improvements in rising hinges; and it consists in a gate or door hinge the lower knuckle of which is-pro vided with double inclines and notches situated diametrically opposite each other, in connection with an upper knuckle having double inclines, and a projection adapted to fit'into the notches of the lower knuckle, when the gate is opened in either direction at right angles to its closed position, as will be hereinafter more fully set forth. j

In the annexed drawings, A A designate the uprights or posts, between which is hung a gate, 15, consisting of two vertical bars, a, and two longitudinal bars, 1), between which may be woven wire of suitable rigidity and of any suitable design. The upper hinge, B, is of the ordinary blacksiniths or hook-andeye pattern, and is,applied to the posts A in the usual well-known manner, with the exception that its pin 0 projects downwardly. Upon this pin is applied a helical metallic spring, 8,.

in such a manner that when the gateis raised by a lower hinge, hereinafter described, it shall be compressed between the knuckles d d of the hinge. The lower hinge, B is a rising hinge, as it is technically called, and

its knuckle f in front of the pin f is provided with double inclines g, adapted to receive a correspondingly-shaped angular projection, i, upon the lower edge of the knuckle j.

When the gate is hung, owing to the doubleinclined walls of the notch g, it may be opened from either side, and when opened will be raised vertically a short distance, thereby compressin g the spring a; consequently when it is released the reaction of the spring will cause the gate to be rapidly and effectually shut.

With a view to holding the gate open when readily appreciated when it is considered that,

in haulingthe crops from afield to the barn, the driveris generally alondand has no one to hold the gate open while he drives his animals through, and consequently is obliged to leave his team to their own guidance at the risk of tearing down the gate, while he holds the same open for their passage.

I am aware that a hinge has heretofore been constructed, in which the knuckles are provided with double inclines, the lower knuckle being also provided with a notch for the reception of a projection in the upper knuckle, and therefore I lay no claim to such invention, broadly, which is incapable of bold in g the gate, when open in either direction, at right angles to its closed position.

What I claim as new, and desire to secure by Letters Patent, is- V In a gate or door hinge, the k-nucklef, pro-- ,vided with double inclines g and notches are, situated diametrically opposite each other, in combination with theknuckle j, havin g double inclines, and projection 2', adapted to fit into,

said notches n, whenthe gate is swung in either direction at right angles to its closed position, substantially as and for the purpose described. v a

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
